A new album of Jimi Hendrix's unreleased studio material has been unveiled - but it is likely to be the last one.

The record, People, Hell And Angels, is the end of a four-decade run of posthumous releases, according to Eddie Kramer, the engineer who recorded most of Hendrix's music during his career.

He said: "Jimi utilised the studio as a rehearsal space. That's kind of an expensive way of doing things, but thank God he did."

The 12 tracks on People, Hell And Angels were recorded from 1968 to 1969 after the Jimi Hendrix Experience disbanded. Many of the songs have been heard in different versions or forms before.

Hendrix died of asphyxia in September 1970 at 27, and the last of his studio albums was timed for the year he would have turned 70.

However, Kramer insisted it wouldn't be the last people would hear of the late star.

He explained: "This is the last studio album, but what's coming up is the fact that we have tremendous amount of live recorded concerts in the vault. A lot of them were filmed, too, so be prepared in the next few years to see some fabulous live performances, one of which I've already mixed.

"We're waiting for the release date - God knows when - but at some point in the future there's a ton of great live material."
